When is Drain Excavation Necessary?
While we always explore “no-dig” trenchless repairs first, excavation is the essential and correct solution for certain types of drain failure. A CCTV drain survey will confirm if you need excavation due to:
Collapsed Drains: The pipe has completely caved in, stopping flow and making lining impossible.
Severe Displacements & Fractures: Pipe joints have shifted so significantly that they can’t be sealed from the inside.
Incorrect Gradient (Backfall): The original pipe was laid incorrectly and doesn’t slope enough (or slopes the wrong way), causing chronic blockages.
Complete System Replacement: Old, deteriorating pipework (e.g., pitch fibre or clay) needs to be fully upgraded to modern uPVC.
New Drainage Installations: Laying new pipes for a property extension, new build, or septic tank installation.
Honest Advice: Excavation vs. No-Dig Repairs
As drainage experts, we are proficient in all forms of repair. Many issues can be fixed with modern “no-dig” methods like drain lining.
However, we will only ever recommend the solution that is right for your specific problem. If excavation is the only way to guarantee a permanent, reliable fix, we will explain why in detail.
Our priority is to provide you with a lasting solution, not a temporary patch.
Our Commitment to You: We use state-of-the-art CCTV drain inspection equipment to thoroughly diagnose the issue.
We’ll show you the footage, clearly mark the damaged section, and present you with a detailed quote outlining both the no-dig and excavation options, along with our expert recommendation.
We will never recommend an excavation unless it is absolutely essential to guarantee a permanent, high-quality repair.

Frequently Asked Questions
How do I know if my drain needs to be excavated?
The only way to be certain is with a CCTV drain survey. The camera footage will clearly show if the pipe is collapsed or too damaged for other repair methods, and our engineer will show you the findings on-site.
Will the excavation ruin my garden or driveway?
We understand this is a major concern. Our team works with the utmost care to minimise the footprint of the dig. Crucially, our service includes full reinstatement of the surface, so we will put everything back to its original condition.
How much does drain excavation cost?
The cost varies significantly depending on the depth of the drain, the length of the repair, and the type of surface being excavated. We provide a detailed, no-obligation, fixed-price quote after a thorough site survey.
How long does an excavation job take?
A typical domestic repair can take anywhere from one to three days. The full timescale will be clearly outlined in your quote, and we will work efficiently to complete the job as quickly as possible.
